Difficult to be certain just looking at your pictures but check the following:-

• Your first order of rotation must be axial to the neck.
• The center needs to be at the base of the head where it joins the neck.
• Orientate the center so that the twisting axis points down the neck
• Twist: Place the green end at the base of the head where it meets the neck. Place the red end at the end of the neck where it meets the body.
• Bend & Side-Side: Green handles pointing towards the head and angled so that all the head is included. Red handles point towards the body.
• For the eyes you'll need to turn off bending.

If you'd like to make the files available I'll be happy to take a look at it if needed.
